Mr. Obama, who made Israeli-Palestinian peace a priority from the outset of his administration, is now the US leader with incongruously bad relations with the Arab world. Here are three key causes of the deterioration in relations – and three steps that the United States can take to mend ties.

Rhetoric vs. reality

President Obama toured the Sultan Hassan Mosque in Cairo with Secretary of State Hillary Rodham Clinton in June 2009, the day he gave his ‘A New Beginning’ speech to the Arab world at Cairo University.

The standout example of the gulf between rhetoric and reality is Obama's lofty speech in Cairo in June 2009 – in which he talked about a new beginning in US relations with the Arab and Muslim worlds, based on mutual respect and understanding.

But it's hardly the only example. On his second full day in office, Obama named former Sen. George Mitchell as his Mideast envoy, raising high hopes. But after scant progress, Mr. Mitchell resigned this past May.

Also playing a role, some say: a sense of US hesitation over what to do as Hosni Mubarak teetered in Egypt early this year.
